This review, “Orion’s new binocular telescope tested,” appeared in the March 2008 issue of Astronomy magazine

For the past 4 decades, I’ve lived by the creed that, for stargazing, two eyes are better than one. If you need convincing, Orion Telescopes and Binoculars makes a strong case with its BT70 binocular telescope.

The BT70’s 20x eyepieces capture 3.2° of sky thanks to their 63° apparent fields of view. Each eyepiece focuses individually.

The BT70 also comes with a removable handle, slide-out dew caps, and a sturdy, foam-fitted carrying case.
